CHICAGO, April 3 /PRNewswire/ --

The Certification Authority/Browser Forum (CAB Forum), the author of the guidelines for issuing Extended Validation (EV) SSL certificates, is pleased to announce that approximately 5,000 EV SSL certificates have been deployed by businesses and organizations worldwide(1) since the introduction of the guidelines last June.

Extended Validation SSL certificates were introduced last year to help businesses and organizations conducting e-commerce, e-banking or e-government to reliably assert their identities to end-users and consumers. EV SSL certificates are issued to entities that complete a rigorous validation process that includes the following criteria:

A team of researchers led by Danish professor Eske Willerslev shows that the ancestors of the North American Indians who came from Asia were the first people in America, and that they were of neither European nor African descent. It also shows that immigration to North America took place approximately 1,000 years earlier than assumed. These findings call for a revision of our understanding of the early immigration route to the American continent.

Willerslev, of the University of Copenhagen, and colleagues recently conducted DNA tests on samples of fossilized human feces found in deep caves in the Oregon desert and came to a conclusion sure to cause debate - the oldest of the droppings have been carbon-dated to be approximately 14,340 years old. Willerslev’s feces samples clearly contain two main genetic types of Asian origin that are unique to present-day North American Indians.

There are many interactions between the Sun and the Earth but one of the most dynamic events is a ‘substorm’ - an explosive reshaping of the Earth’s outer magnetic field.

To better understand substorms, scientists in Europe and North America are studying them from space using the Time History of Events and Macroscale Interactions during Substorms (THEMIS) satellites launched by NASA in 2007 and from the ground using a network of all-sky cameras.

University of Lancaster solar-terrestrial scientist Dr Emma Woodfield gave a talk at the Royal Astronomical Society National Astronomy Meeting in Belfast and presented the first few months of results from the Rainbow cameras newly installed in southern Iceland that complement this network.

Reshaping of the DNA scaffolding that supports and controls the expression of genes in the brain may play a major role in the alcohol withdrawal symptoms, particularly anxiety, that make it so difficult for alcoholics to stop using alcohol.

DNA can undergo changes in function without any changes in inheritance or coded sequence. These "epigenetic" changes are minor chemical modifications of chromatin -- dense bundles of DNA and proteins called histones.

"This is the first time anyone has looked for epigenetic changes related to chromatin remodeling in the brain during alcohol addiction," said Dr. Subhash C. Pandey, professor and director of neuroscience alcoholism research at the UIC College of Medicine and the Jesse Brown VA Medical Center in Chicago, the lead author of the study.

A new study by researchers at UC Davis shows how our very short-term "working memory," which allows the brain to stitch together sensory information, operates. The system retains a limited number of high-resolution images for a few seconds, rather than a wider range of fuzzier impressions.

Humans rarely move their eyes smoothly. As our eyes flit from object to object, the visual system briefly shuts off to cut down visual "noise," said Steven J. Luck, professor of psychology at the UC Davis Center for Mind and Brain. So the brain gets a series of snapshots of about a quarter-second, separated by brief gaps.

The working memory system smoothes out this jerky sequence of images by retaining memories from each snapshot so that they can be blended together. These memories typically last just a few seconds, Luck said.
